12.1-07-7
Situation 2: Momentary power loss, or power current too low and unstable, or power supply
sliding down because of sudden heavy load.
Pr. 07-13=2 “dEb active, DC BUS voltage returns, output frequency returns” and power
recovers.
During the dEb deceleration (includes 0 Hz run), if the power recovers higher than dEb
return level, the drive maintains the frequency for the set time of Pr. 07-14 (default = 3 sec.)
and then accelerates again. The dEb warning on the keypad clears automatically.
